The chemical symbol for Niobium is Nb. Gadolinium occurs in different forms of isotopes naturally, among which the relatively stable are with the mass numbers 154, 155, 156, 157, 158 and 160 along with one radio isotope 152 Gd. We can determine the neutron number of certain isotope. Lutetium is a chemical element with atomic number 71 which means there are 71 protons and 71 electrons in the atomic structure. The chemical symbol for Silver is Ag. Its properties are thus intermediate between those of chlorine and iodine. Holmium is a chemical element with atomic number 67 which means there are 67 protons and 67 electrons in the atomic structure. These two forces compete, leading to various stability of nuclei. Mass numbers of typical isotopes of Gadolinium are 154-160. The chemical symbol for Gadolinium is Gd. The commercial use of beryllium requires the use of appropriate dust control equipment and industrial controls at all times because of the toxicity of inhaled beryllium-containing dusts that can cause a chronic life-threatening allergic disease in some people called berylliosis.
